MT48LC4M16A2P-7E:J TR

The MT48LC4M16A2P-7E:J TR is a 64 Mbit synchronous DRAM (SDRAM) device manufactured by Micron Technology Inc., organized as 4M × 16 with a parallel memory interface. It delivers PC133-class performance with a 133 MHz clock frequency and is supplied in a compact 54-pin TSOP II (400 mil / 10.16 mm width) package.

This SDRAM is suited for system memory implementations that require a fully synchronous parallel DRAM in a small TSOP profile, operating from a single 3.0 V to 3.6 V supply and specified for commercial temperature range (0°C to 70°C).

Key Features

• Core / Architecture SDR SDRAM with fully synchronous operation; all signals registered on the positive edge of the system clock and internal pipelined operation for column-address changes every clock cycle.
• Memory Organization 64 Mbit capacity arranged as 4M × 16, providing parallel data organization for system memory arrays.
• Performance & Timing PC100- and PC133-compliant timing with a 133 MHz clock frequency. Product timing includes an access time of 5.4 ns and a word/page write cycle time of 14 ns.
• Burst & Bank Features Internal banks to hide row access and precharge; programmable burst lengths (1, 2, 4, 8, or full page) and support for auto precharge modes.
• Refresh & Power Management Auto refresh capability and self-refresh modes (standard and low power variants noted in datasheet options) for maintaining DRAM state during idle periods.
• Interface & I/O Parallel memory interface with LVTTL-compatible inputs and outputs for system-level interfacing.
• Power Supply Operates from a single 3.3 V ±0.3 V supply (specified 3.0 V to 3.6 V).
• Package & Temperature 54-pin TSOP II (0.400" / 10.16 mm width) plastic package; commercial operating temperature range 0°C to 70°C.

Typical Applications

• Embedded Systems — Parallel SDRAM for system memory in compact embedded platforms that require a TSOP II footprint and PC133-class timing.
• Legacy and Upgrade Designs — Drop-in SDRAM option for designs using parallel SDRAM architectures with 3.3 V supply requirements.
• Industrial Electronics — Memory for commercial-temperature equipment where a 54-pin TSOP II package and standard refresh modes are suitable.

Unique Advantages

• PC133-Class Timing: 133 MHz clock frequency and PC100/PC133 compliance enable integration into systems targeting these timing standards.
• Compact TSOP II Package: 54-pin 400 mil TSOP II offers a small board footprint for space-constrained designs.
• Flexible Burst Modes: Programmable burst lengths and internal pipelining support efficient block transfers and predictable latency.
• Standard Power Envelope: Single 3.3 V supply simplifies power rail design and compatibility with common system voltages (3.0 V–3.6 V).
• Robust Refresh Controls: Auto refresh and self-refresh options maintain data integrity during normal and idle operation modes.
